Folder goes out of scope when the function exits so you should not return a pointer to that memory. Allocate the memory using new() or allocate the buffer in the calling function and pass it to this function
System.IO.Path.IsPathRooted() does not behave as I would expect

As indicated by Josh, the problem is because, you are returning address of local object. Create it on heap, and return it.

This is in fact very bad coding practice, It causes unnecessary multiple calls of a functions.
Modify it to,
size_t n =wcslen(Folder);
for(n; n >= 0; n--)

Actually it doesn't. wcslen() is only called once.

Add handler for it.
Are you sure ON_WM_CLOSE() is there in message map ?
|
|
|
|
|
Yes ofcourse I have added.

Hello,
I have been searching for this but can't find any answer. I would like my app to be able to handle left-click on popup menu (not menu items). Suppose my menu is:
Item 1
Popup > PopupItem1
PopupItem2
Item2
Everybody known how to handle left-click on Item1, Item2, PopupIem1 and PopupItem2. But how can one detect a left-click on the "Popup" item? Is this feasible with a regular CMenu instance?
Thanks!

Hope I understood you!
This is from the documentation...
TPM_LEFTBUTTON If this flag is set, the user can select menu items with only the left mouse button.
TPM_RIGHTBUTTON If this flag is set, the user can select menu items with both the left and right mouse buttons.

|

No sorry this is not my point. This will not add a notification if the user clicks on the "Popup" item. This will only change the behavior when clicking on "real" menu items.

Hi.
In my application I have added a listbox on a dialog box. This list contain numbers of elements that user has to scroll so much to see all the contents.
I want to minimize the scrolling efforts of user and I want to provide auto scrolling to the list box. The elements of the list box should get scroll automatically when user movies the mouse pointer over scroll bars of the list.
How I can proceed to achieve this?
Thanks

What would be the difference between an registered dll and a normal dll that doesn't have to be registered, would there be any performance differences?
Many Thanks

Assuming the DLL's are the same as far as their core code is concerned, No.

Yes the code would be the same ... Thanx for clearing that one up John.

Normal dll should be present in Exe Current Directory or environment path.. but no such compulsion with registered dll as it path is stored in registry
|

So that is the difference between the two? (in a nutshell)
Thanks for the response.

Hello,
I have a Dialog, where in I show some text and draw some images using DrawText() and Draw(..) functions respectively.
Now I need to introduce an IEControl on this dialog. I wish the IE control to behave as if, its the background of my dialog, i.e. when I draw text on my main dialog, some part of the text is present on the main dialog and some part of the text spills over the IE control(this behavior is desired.) however, I wish to show my text in the foreground and the IE control to be on the background.
However windows is not providing any APIs for definind Z-Order for a child window and the text out on the dialog.
Any pointers in this regard will be highly appreciated.
Thanks
Suyash

No, there's no Z-order for drawing on a window. It's up to you to make sure you draw on top
of whatever you want the text to be on top of.
I'm not sure what "IEControl" you are using so I'm not sure how you could potentially know when
it's appropriate to draw the text.

What is difference between File pointer and File Descriptor?
|
|
|
|
|
a file descriptor is an unique number managed by the system itself to identify the file opened.
in your code, you don't get it. you get a FILE* (file pointer) to a copy of the opened file mounted in memory
you actually never work directly on the hard disk file, but on its copy into memory

Hi guys
I'm trying to figure out how to make a template class History. This class should be able to record history moves.(for any application). e.g. a history of changed in an editor, or a history of URLs in a web browser etc.
This is what i came up with so far.
<br />
#include < stack ><br />
#include < iostream ><br />
#include < string ><br />
<br />
using namespace std;<br />
<br />
template < typename E > <br />
class history<br />
{<br />
private:<br />
stack < E > back_list; <br />
stack < E > forward_list;<br />
<br />
public:<br />
history();<br />
void add_entry(const E & entry);<br />
E & undo();<br />
E & redo();<br />
bool no_undo();<br />
bool no_redo();<br />
};<br />
<br />
template < typename E ><br />
void history < E >::add_entry(const E & entry)<br />
{<br />
back_list.push(entry);<br />
while(!forward_list.empty())<br />
{<br />
forward_list.pop();<br />
<br />
}<br />
}<br />
<br />
template < typename E > <br />
E & history < E >::undo()<br />
{<br />
E entry;<br />
if(!back_list.empty())<br />
{<br />
entry = back_list.top();<br />
back_list.pop();<br />
forward_list.push(entry);<br />
<br />
}<br />
<br />
return(entry);<br />
}<br />
<br />
template < typename E > <br />
E & history < E >::redo()<br />
{<br />
E entry;<br />
if(!forward_list.empty())<br />
{<br />
entry = forward_list.top();<br />
forward_list.pop();<br />
back_list.push(entry);<br />
}<br />
return(entry);<br />
}<br />
<br />
template < typename E > <br />
bool history < E >::no_undo()<br />
{<br />
if(back_list.empty())<br />
return(1);<br />
else return (0);<br />
}<br />
<br />
template < typename E > <br />
bool history < E >::no_redo()<br />
{<br />
if(forward_list.empty())<br />
return (1);<br />
else return (0);<br />
}<br />
<br />
<br />
<br />
void main()<br />
{<br />
history <int> his;<br />
his.add_entry(2);<br />
int out;<br />
out = his.undo();<br />
cout<<out;<br />
<br />
}<br />
<br />
I get no compilation errors but as soon as i try to run it i get:
<br />
Linking...<br />
history.obj : error LNK2001: unresolved external symbol "public: __thiscall history<int>::history<int>(void)" (??0?$history@H@@QAE@XZ)<br />
Debug/history.exe : fatal error LNK1120: 1 unresolved externals<br />
Error executing link.exe.<br />
<br />
history.exe - 2 error(s), 0 warning(s)<br />
Any ideas of i'm doing wrong?
It's the first time i'm using template so i'll appreciate any help.
Thank in advance.
